The commodore came out with a variety of wheels as standard and optional fitment and it’s all specified on the Road Vehicle Descriptor for each variant. So search through the list below to find the RVD for your specific year and model variant and that RVD will list
standard and
optional rim and type sizes
front and
rear (or
both). The RVD also lists ride height amongst other things...

If the RVD lists staggered wheels, not sure it’s the case with SSV, you theoretically can’t reduce the rear rim width but that view is a little contentious for some on this forum.... Once you know what is standard and optional for your model variant, you can then adjust aspect ratios and widths as allowed under modification rules...
Oh, and SS doesn’t have Brembo brakes but not sure if SSV is the same or gets the Brembos (the redline does). If you don’t have factory Brembos, that gives you a more freedom as to what size wheel will actually fit over your brakes as factory 18“ rims will fit over non Brembo brakes. And 18” rims will provide a more compliant ride with the matching height sidewall tyres (cheaper to buy as well).
But for many it all comes down to fashion so you can take it from here
PS: not all after market rims are built the same... Factory 20” rims are drop forged and much much stronger than cheap semi forged or spun rims. I think Simonds are spun and known for buckling...
Some people buy cheap factory drop forged wheels but they are counterfeit rims and just look factory but they aren’t strong... You do get what you pay for...
